T aZZ whom it may concern: Be it known that I, EDWARD E. BITTER, a

, citizen of the United States, residing at Milton, in the county of Northumberlandand State of Pennsylvania, have invented a new and useful Nozzle, of which the following is a specification.

This invention relates to nozzles of thatclass which are largely employed for street proved means whereby the size of the slit or escape-opening may be conveniently regulated, whereby the range or scope of adjust,-

- ment may be large, and whereby leakage shall be avoided.

With these and other ends in view the inventlon consists in theimproved construction, arrangement, and combination of parts, which will be hereinafter fully described, and particularly pointed out in the claims. t In the accompanying drawings, Figurel is a perspectlve view of a nozzle constructed in accordance with the principles of my invention. Fig. 2 is a vertical sectional view of the same Fig, 3 is a sectional View taken at right angles to Fig 2. Fig. 4 is a sectional view taken on the line 4 4: in Fig. 2.

Corresponding parts in the severalfigures are lndicated by similar numerals of reference.

My improved nozzle may be described as comprlsing a section of pipe 1, closed at one end, as shown at 2, and screw-threaded at its opposite end, as shown at 3, for connection w th a supply-pipe. The pipe-section or body 1 lsprovided with a laterally-extending nipple 4:, the perforation through which, 5, forms a bearing for a shaft 6, carrying at its inner end a disk 7 which is accommodated in a recess or enlargement 8 at the inner end of the nipple. The outer end of the shaft 6 carries an operating lever or handle 9, between which and the end of the nipple a spring 10 is inter- Serial No. 191,711. (No model.)

posed to force the shaft in an outward direction, and'thus to afford frictional contact between the outer side of the disk 7 and the adjacent side of the recess '8, whereby a practically water-tight joint is formed. V v

' The pipe-section or body 1 is provided adjacent to the closure 2 with a peripheral slit or opening 11', which may be of any desired length and width to admit of the passage of the maximumquantity of fluid which it may be desired at any time to discharge. Interiorly of the body or pipe-section 1 is disposed a slidable sleeve 12, composed of an elastic band of spring-steel or other suitable material,

which'is bent to cylindrical shape, so as to fit in the pipe-section or body 1, within which it expands, so as tolie closely in contact with the walls thereof, the ends of the band forming the sleeve being when the latter is expanded slightly spaced apart, as will be seen at 13. This spaced portion is preferably disposed diametrically opposite to the slit or opening 11, and to the said sleeve is secured a flange 14, which is movable in the slit 11 and which limits the movement of the sleeve 12. This flange 141: is adapted to abut upon the edge of the slit 11 adjacent to the closure 2 in such a manner as to' form a practically water-tight closure.

In the wall of the sleeve 12 is formed an L- shaped slot or notch 15, whichi's engaged by a pin 16, which extendsfrom the disk 7 at the inner end of the shaft 6. It will thus be seen that by partially rotating the shaft 6, by means of the lever or handle 9, the sleeve 12 may be I pable of being manufactured at a comparatively trifling expense, and it may be readily connected with any suitable source of supplysuch as, for instance, a tank for streetsprinkling purposes supported upon wheels. The improved nozzlewhich forms the subject of my invention may be used in any position that is, the pipe-section which constitutes the main body thereof may be placed either in a vertical or in a horizontal position, so that the discharge through the slit 11 shall be properly directed. The operating lever or handle 9 may be connected in any suitable manner with operating means located at a distance from the nozzle, so that adjustment of the size of the discharge-opening or the closure of the lattermay be conveniently effected at any time. The elastic nature of the expansionsleeve 12 enables leakage to be avoided, and it is obvious that wear upon the said sleeve and upon the interior surface of the pipe-section forming the body of the device will be constantly and automatically compensated for.

I desire it to be understood that while I have in the foregoing described a simple and preferred form of my invention I do not necessarily limit myself to the precise structural details herein shown and described, but reserve a right to such changes and modifications as lie properly within the scope of my invention and which may be resorted to Without departing from the spirit or sacrificing the utility of the same.

Having thus described my invention, I elaim- 1. In a device of the class described, a cylindrical body having a closure at one end, a slit adjacent to said closure, and an interiorlydisposed longitudinally-movable sleeve having a flange movable in said slit.

2. In a device of the class described, a cylindrical body having a closure at one end and a slit adjacent to said closure, an interiorlydisposed longitudinallymovable and laterally-expansible sleeve, and a flange upon said sleeve engaging the slit in the cylindrical body.

3. In a device of the class described, a eylindrical body having a closure at one end and a slit adjacent to said closure, an expansible sleeve longitudinally movable in said body and having a flange engaging the slit, and means for effecting the longitudinal adjustment of said sleeve to form a partial or complete closure for the slit.

4. In a device of the class described, a cylindrical body having a laterally-extendiug nipple and provided with a closure at one end and with a slit adjacent to said closure. :1 longitudinally-movable, expansible sleeve within said body adapted to form a closure for the slit therein, and a shaft journaled in the nipple and having engagement with the sleeve whereby the latter may move longitudinally within the cylindrical body.

5. In a device of the class described, a cylindrical body having a closure at one end, a slit adjacent to said closure and a laterallyextending nipple, a sleeve slidable within said body and adapted to form a closure for the slit, said sleeve being provided with an L- shaped slot, and a shaft journaled in the nipple and having a pin engaging said slot.

6. In a device of the class described, a cylindrical body having a closure at one end and a slit, a sleeve longitudinally slidable in said body and adapted to form a closure for the slit, a nipple extending laterally from the body and having abore enlarged at its end, a shaft journaled in said nipple and having a disk engaging the enlarged portion of the bore, a pin extending from said disk and engaging a slot in the slidable sleeve, a handle upon the shaft, and spring means to force the latter in an outward direction.

In testimony that I claim the foregoing as my own I have hereto aflixed my signature in the presence of two witnesses.
